The unit-cell contents of (I). Non-H atoms are shown as 50% probability displacement ellipsoids and H atoms as small circles of arbitrary radii. All H atoms other than those involved in hydrogen bonding (dashed lines) have been omitted. Selected atoms are labelled. [Symmetry codes: (i) x, ½ − y, ½ + z; (ii) 1 − x, 1 − y, 1 − z; (iii) 1 − x, ½ + y, ½ − z.] |
